Friction Rock Stabilisers

The Design (click here) of Skema's Friction Rock Stabilisers allows them to tighten as lateral rock displacement occurs, enhancing their yield capabilities. After installation (when ground shifts can loosen an ordinary bolt), the Friction Rock Stabiliser tube grips more tightly.

Days, weeks or months later, when the average conventional bolt becomes ineffective and needs retorquing, a typical stabiliser tube retains its load-bearing characteristics - it never needs tightening. The tubular structure and high strength of the Friction Rock Stabiliser allows it to conform to rock displacements.

All Friction Rock Stabilisers are assembled using a state-of-the-art robotic welder, ensuring that the end product is built to consistent high levels of quality.

In order to ensure that Skema's friction rock stabilisers are able to perform und er some of the most stringent conditions, an independent Risk Assessment was undertaken. Shoddy workmanship and poor quality control can cost lives, and Skema is acutely aware of this.

When one manufactures a product upon which peoples lives depend, it is important to ensure that quality is not just taken for granted. With this in mind, Skema has made it mandatory that in-house destructive tests are conducted on a regular basis to ensure that the highest levels of quality are maintained.

In production any number of parameters can change, and only through ongoing destructive testing can you be assured that your friction rock stabilizers adhere to the maximum level of safety.

In order to improve durability Skema has an in-house hot-dip galvanising facility, which improves the life of the friction rock stabiliser quite significantly over traditional steel stabilizers.
